FLOAT-VALVE.

citizen of the United States, residing atjDe-Y catur, in the county of Macon and State of Illinois, have invented new and useful Im1 provements in Float-Valves, of which the following is a specification.

My invention consists of a float valve of the ball cock type for use in connection with tanks generally.

The object of my invention is to provide a valve which is adaptedfor ready and oon- .venient use with Hush?tanks,lsuch as areI4 commonly used, andin which the presence otlush device mechanisms makes it desirable that the float lvalve used be capable of adjustment to aposition in which the other devicesI present will not interfere with its operation, and in which it may have free play to operate to open and close the valve. I'Vhile having the special purpose named, however, my invention is capable of application to the float and regulating valves of tanks generally.

In the attainment of the prime object of my invention I have mounted the valve in a lateral branch connection with the riser or supply pipe which supplies water to lthe tank, and have given the lateral branch connection a swiveled adjustable connectionv with the riser, so that it and the valve are adjustable with respect to the riser. Thus the ball or other oat, and lever of the valve, as well as the valve, may be moved to any desired position and held there.

I have shown one embodiment of my invention applied to a small Hush tank in the drawings.

Of the drawings Figure 1 is a sectional elevation of the tank showing the float valve of my invention applied, with certain parts of the lateral branch connection broken away in order to show its interior construction; Fig. 2 is a plan view with certain parts of the lateral branch connection in section 1n `order tjo show the valve construction, and

passes through the bottom of the tank.

12 is the lateral branch connection carrying the float valve which is designated 13,

14 is the float lever and 15 a ball connected therewith.

As is usual in float valves, and as clearly shown in Fig. 2 the rise of the. float is adapted to close the valve, while a lowering of the float, due to a lowering of the level of water in the tank, is adapted to open the valve.

The lateral branch connection 12 is swiveled onv the upper end of a stud 16 screw threaded to the riser 11. Thus the lateral branch 12 has a swiveled connection with, or with relation to, the riser or supply pipe. rI`he lower end or Ycap end of this stud, is provided with an extended base 17 adapted to rest against the bottom of the tank or against the packing, as shown, in order to make a water tight joint, and above the portion 17 is formed hexagonal in shape to accommodate a wrench. Above the cap portion the stud is reduced in cross section to form a shoulder 18 and the journal portion of the stud 19. This cap stud is centrally cored out, to communicate with the riser and provided with lateral openings 20. The lateral branch connection l2 is journaled on the upper end 19 of the stud as shown, and communicates with the riser through the lateral openings in the stud. Suitable packings'21' socketed as shown tobetter accommodate and hold the packings 21. The valve in the lateral branch comprises the seat 23, the stem 24 having a coarse screw threaded Vconnection with the branch and the valve disk 25 on the stem. Constructed in this manner, the valve of my invention may be laterally adjusted around the riser as an axis to any position on the dotted line circle shown in Fig. 2. In any of these positions, the float acts to operate the valve in the usual marir` ner. Moreover the valve may be repaired whennecessary by simply removing the lateral branch which carries `it and Without. breaking the supply pipeconnection;

As shown in Figs. 2 and 3 the float itself is connected to the stein of the valve by intermeshing [sert-ations or corrugations on the stemiand the Hoet respectively, so that the Hoa-t may be taken ofi' and replaced in any position whatsoever with respect. to the stem, thus giving the oat an angular' adjustment with respect to the valve,and enabling one to regulate the level of Water within the tank.

The form of the end 16 of the stud connecting with the. riser l1 may be anything suit/ed to the purpose,

The combination with a tank, of a supply pipe therefor,l

the end of which proJects through the bottom thereof, a straight hollow stud located: within the tank and detachably swiveled .upon said stud .said stud7 means for connected to tl ,ndlof the supply pipe',V a valve casing detachably connected to and and in continuous communication with. the supply pipe through holding said valve casing 1n place upon the stud, a. valve carried by said swiveled @using and operating in a line substantially at right angles to the laxis of said stud, and a oat connected to the stein of said valve, substantially as described.

In testimony whereof I have hereunto set 30 my handvin presence oftwo subscribing Wit nesses.
